  Log:
  SVN rev 194387 on 2009-06-17 18:55:29Z by snb
  
  Keep dirhash tailq locked throughout the entirety of ufsdirhash_destroy() to fix
  a potential race pointed out by pjd. Also use TAILQ_FOREACH_SAFE to iterate over
  dirhashes in ufsdirhash_lowmem(), so that we can continue iterating even after a
  dirhash is destroyed.
